Very nice location, near all facilities, malls and bts - 10 min walk. There is also a shuttle service that brings to a mall and bts station. The staff working in the building are very friendly.
We enjoyed using the fitness center which has good and new equipment, and a wonderful view. There is also a confortable reading room for work. The swimming pool looks nice but it is not heated, so you can't really enjoy it - the water is really cold. All these facilities close at 10 pm, it was a little bit early for us.
Regarding the appartment itself - it is ok if you stay few days, but if you are planing a long stay as us (a couple and we stayed 1 month) it is not very convinient as it is quite small. We found that all the bedding is very bad (pillows, mattress, bed..), so we finished by sleeping on the floor on the mattress topper. And the AC was leaking. But we enjoyed the view from the balcony (high floor and unobstructed view on the city) and the Wifi is high speed (more than 600 Mb).
